MATTRESS.

Application filed April 27, 1927. Serial No. 186,901.

Our invention relates to'mattresses, more particularly bed or likemattresses, and the objects of our invention are: first,to provide amattress of this class which has no external tufting; second, to providea mattress of this class which has no dust-catching external plaits,third, to provide a mattress of this class which is provided withlongitudinal and transverse cross reinforcing on the inner side of themattress casing; fourth, to provide a mattress of this class which isprovided with a plurality of cross folds at opposite sides inside thiscasing at the points where they are tied for reinforcing and supportingthe tie cords; and fifth, to provide a device of this class which issimple of construction, durable, smooth surfaced, and sanitary.

WVith these and other ob 'ects in view, as will appear hereinafter, ourinvention con sists of certain novel features of construction,combination and arrangement of parts and portions, as will behereinafter described in detail and particularly set forth in theappended claims, reference being had to the accompanying drawings and tothe characters of reference thereon, which form a part of thisapplication, in which:

Figure 1 is a perspective view of a fragmentary portion of our mattress;Fig. 2 is an enlarged fragmentary perspective view of one corner of theinterior of the mattress casing, with the stuffing removed, and Fig. 8is a further enlarged fragmentary sectional view thereof through 33 ofFig. 2.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

The casing 1, reinforcing strips 2 and 3, and tie cords 4L, constitutethe principal parts and portions of our mattress.

The casing 1, which is preferably made of cloth, is composed of top andbottom portions 1 secured at their edges to side strips 1". The sidestrips 1 and the top and bottom portions 1 are sewed together so astoplace the edges of the seams toward the interior of the casing.Similarly the side strips are sewed together, as shown best in Fig. 2 ofthe drawings. On the top and bottom portions 1 of the mattress 1 areparallel, transversely spaced apart plaits 1 on which are securedreinforcing strips 2. The strips 2 are preferably made of cloth doubledagainst itself forming a fold and sewed to the plaits 1, preferablysewed at the same time the plait is being made. Similar strips 3 aresewed to parallel,

plaits, transversely,

longitudinally extending, spaced, apart plaits 1 ,which cross the plaits1 and strips2; at

such intersections the strips 2 are tucked with the plaits-l all ofwhich forms part of the plait 1 as shown best in Fig. 3 of the drawings,At the intersections of the reinforcing strips there are eightthicknesses of material. There the plaits 1 and 1 cross, there aretwelve thicknesses of material, thereby forming strong reinforced pointstransversely and longitudinally spaced apart. With the correspondingintersections on both the top and bottom portions in approximatelyvertical alignment stu'liing is placed within the mattress and the endsof a cord 4 are threaded through the top and bottom portions of thecasing, so that the ends straddle the'junction of the plaits andreinforcing strips. The free ends of the cords 4 which extend throughthe bottom portion 1 of the casing are drawn tight and tied. The cord 4thus forms a loop, which straddles the strongly reinforced Junction ofthe two plaits with their reinforcing strips. It will be noted that themattress as formed requires no external tufting to prevent the cordsfrom tearing or pulling through the mattress casing.

Though we have shown and described a particular construction,combination and arrangement of parts and portions, we do not wishto belimited to this particular construcsire to include in the scope of ourinvention,

the construction, combination and arrangement substantially as set forthin the appended claims.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:

1. In a smooth faced externally tuftless mattress of the classdescribed, a casing composed of top, bottom and side portions,longitudinally extending, spaced apart plaits, longitudinally, inwardlyextending, spaced apart reinforcing strips secured to said plaits bystitching through saidtop or bottom portions, plaits, reinforcingstrips, throughout the length of said plaits and reinforcing strips,transversely extending, spaced apart inwardly extending, spaced apartreinforcing strips secured to said plaits by stitching through said topor bottom portions, plaits, reinforcing strips, throughout the length ofsaid plaits and reinforcing strips, stalling within said casin and tiecords without exterior tufts, QXtilQ tion, combination and arrangement,but deing thronghfsztid top and bottom portions adapted to straddle thecorrespondingintersection of said reinforcing strips and said plaits ofsaid top and bottom portions and hold seamstress: in its desird"shapef2.
